Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a window glass structure, and more specifically, to a window glass structure that is constructed of double-glazed glass and that allows viewing from only one side. Regarding glass structure.

[Prior Art] Hitherto, there has been no window glass that allows viewing from only one side in a strict sense. However, methods that attempt to achieve a similar effect are those that attempt to ensure only visibility from inside the room as necessary by using shields such as curtains and blinds made of thin fabrics such as lace. There is. In addition, by coating the surface of the glass plate with a highly reflective metal film, etc., the reflected image on the bright side blocks the reflected image on the dark side due to the difference in illuminance between the inside and outside, so that it can be seen through only from one side. There are also things that can be done.

[Problems to be solved by the invention] However, in the case of such conventional technology, since the transmission of light is the same in both directions, in order to be able to see through from only one side, It was necessary to create a difference in illuminance brought about by the relative strength of light indoors and outdoors.

In other words, in order to ensure some degree of transparency from only one side, you must stand on the side of a relatively dark place and look through the side of a relatively bright place, and one side, which is the side to be seen through, must stand on the side of a relatively bright place. There was an inconvenience that it had to be brighter than the transparent side.

[Purpose of the invention] In view of the above-mentioned problems of the prior art, the purpose of the invention is to
An object of the present invention is to provide a window glass structure that can ensure transparency only on one side.

[Means for Solving the Problems] In order to achieve the above object, the present invention was constructed as follows.

That is, the present invention provides a window glass structure in which a plurality of glass plates are arranged at regular intervals, and a shielding material is provided in the space formed between at least one glass plate. This shielding material has a through-hole array surface in which a large number of through holes are regularly arranged in multiple stages at regular intervals in the vertical direction, and the shielding material has a through-hole array surface on the transparent side. One surface is a dark colored surface, while the surface to be seen through is a light colored surface, and the above-mentioned shielding material becomes vertical when a tensile force is applied in the vertical direction; When the surface is not stiff, each surface with rows of through holes is located in a substantially horizontal direction, and the entire surface is bent in a zigzag shape with a positional relationship that allows the lower part of the dark colored surface side to be seen through. The structure is unique in that it is configured so that.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows an example of the shielding state of the window glass structure according to the present invention. A shielding material 3 made of a suitable flexible thin plate member is interposed therebetween depending on the size of the space. This shielding material 3 is formed with a through-hole row surface 7 in which a large number of through-holes 4 having an appropriate shape such as a dot shape or a slit shape are arranged in multiple stages at regular intervals in the vertical direction. . In this case, when the through hole 4 is dot-shaped, its diameter is 2 to 5 mm.
It is preferable that the width be about 2 to 5 mm, and if it is slit-shaped, it is preferable that the width is about 2 to 5 mm. Further, it is desirable that the aperture ratio of the through holes to the total surface area of the shielding material 3 is set in a range of about 20 to 70%.

The shielding material 3 formed in this way has a dark-colored surface 5 on one surface located on the indoor side, and the other surface located on the outdoor side, which is the side to be seen through, when the indoor side surface is the see-through side, for example. A bright color surface 6 is provided on each surface by forming a coating film. Of the dark-colored surface 5 and the light-colored surface 6, the brightness of the dark-colored surface 5 is set to about 0 to 6 from the viewpoint of imparting effective transparency, and the brightness of the bright-colored surface 6 is set to about 0 to 6. It is preferable to form by appropriately combining those having a number of about 7 to 10 (all expressed in Munsell scale). In particular, the bright color surface 6 is desirably formed of a coating film with high light reflectance from the viewpoint of imparting more effective transparency only to the dark color surface 5 side.

On the other hand, when no vertical tensile force is applied to the shielding material 3, the through-hole array surface 7 is always located in a substantially horizontal direction, and the through-holes 4 are inserted from the dark-colored surface 5 side. It is formed in such a way that the entire body is bent in a zigzag shape, so that the lower part of the bright color surface 6 side can be seen through.

Next, the operation of the present invention constructed in this manner will be explained.

An example of the case where the window glass structure according to the present invention is arranged such that the dark-colored surface 5 of the shielding material 3 is located on the indoor side and the light-colored surface 6 is located on the outdoor side, as shown in FIG. Explain. In this case, normally only the lower part of the outdoor area can be seen from the indoor side through the through holes 4 of the perforated surface 7 which is bent and in a horizontal state, and from the outdoor side,
As shown in FIG. 2, only the bright color surface 6 can be seen, and it is virtually impossible to see through the inside of the room.

On the other hand, as shown in FIG. 3, when the shielding material 3 is made vertical by being forcibly pulled in the vertical direction by an external force, as is clear from FIG. It is possible to horizontally see through the outdoor side, which is the opposite direction, from the indoor side. At this time, the person on the indoor side sees the outdoors from the dark-colored surface 5 side, and therefore can clearly see the outdoors through the through hole 4 without being obstructed by the shielding material 3. On the other hand, those who are outside the room will see the room from the side of the light-colored surface 6, so they will be misled by the brightly painted surface of the shielding material 3 and
It becomes difficult to see through the room, making it difficult to see inside the room.

Therefore, transparency can be provided only on one side without being affected by relative illuminance differences such as indoors and outdoors.

Note that by releasing the tensile force, the shielding material 3 can be immediately returned to the zigzag-shaped bent state shown in FIG.

In addition, in the present invention, when the light-colored surface 6 of the shielding material 3 is formed of a coating film with high light reflectance, by placing it on the outdoor side, it has a heat insulating effect that blocks sunlight heat during the day. You can also get

[Effects of the invention] As described above, according to the invention, normally it is not possible to see through the opposite directions from inside and outside the room, similar to when blinds are closed, and the shielding material cannot be used vertically. When it is stretched, it is possible to ensure transparency only on the viewing side without being affected by the relative illuminance difference between the viewing side and the side to be viewed, so for example, if the viewing side is indoors, By setting the side to be viewed outside the room, privacy can be more securely protected.
